There are no medications that can change the results of the Hepatitis B 2.5 test. There are no medications that can turn the Hepatitis B surface antigen negative or cause a false-positive or false-negative test for Hepatitis B. However, there are medications that can control the activity of the virus and protect the liver cells. After a diagnosis of hepatitis B infection is made, further tests of liver function, hepatitis B viral load, liver ultrasound, alpha-fetoprotein, and degree of liver fibrosis should be performed to determine if treatment is needed. If there is liver damage, fibrotic changes in the liver tissue, or cirrhosis, the patient should consult a specialist for treatment under the direction of the physician.
